Civil War wasn't all about slavery

I disagree with Mr. Pitts that the cause of the Civil War was all about slavery.

I challenge Mr. Pitts to answer the following questions:

1. If the war was about slavery, why was West Virginia admitted to the Union in 1863 (during the War) as a slave state?

2. Why didn't slavery end when the war was over? At the conclusion of the war, slavery only ended in the 11 states that had rebelled. The other slave states, such as Maryland and Delaware, did not become free until the passing of the 13th Amendment, eight months later.

3. Why didn't the Emancipation Proclamation from Abe Lincoln free all of the slaves? Lincoln's proclamation only freed the slaves in the 11 rebelling states.

4. Robert E. Lee had spoken out against slavery in the 1850s. Why didn't he take command of the Union Army when offered the command if the war was about slavery?

5. If the war was about slavery, why did Lee accept command of the Southern Army?

7. Also in Union Mills, why did William Shriver, who opposed slavery, support the South and his six sons serve in the Confederate Army?

8. Less then 1 percent of the population owned slaves, why would the other 99 percent risk their lives for an institution where they had nothing to lose?

9. What caused the Draft Riot in New York City?

Also, Mr. Pitts fails to inform the readers that there were free blacks in the country in 1860. Some of these free blacks owned black slaves, including in Maryland. For example, in 1860 in New Orleans there were 10,689 free blacks. Among them, 3,000 of those free blacks owned black slaves.
